Experience

Amazon

April 2025 - Now

Software Engineer II, AI Infrastructure

Bellevue, WA, USA

Architected Kubernetes-based LLM inference infrastructure (vLLM, SGLang) using helm charts and LeaderWorkerSet to reliably serve 100B+ parameter models in production, reducing NVMe model-load latency by 40% and improving startup stability at scale.
Built a HPC capacity management portal (Next.js/React) with automated AWS resource validation (VPC/ENI), eliminating manual checks and preventing failed scale-up events.
Led early adoption of Agentic AI by building MCP auto-discovery tooling and custom agents for Amazon Kiro CLI, enabling faster developer workflows and accelerating AI-native infrastructure adoption across teams.
Mentored engineers on the team to deliver a cloud-native observability tool for job failure visualization that significantly reduced infrastructure troubleshooting time.

Software Engineer II, Last Mile Transportation Technology

Bellevue, WA, USA

Engineered next-gen ML-based capacity planning system (UI/API/ML Orchestration), expanded the system to US, MX, and CA markets. Reduced 52-week cost forecast errors to <20% and slashed planner override rates to <20%, directly optimizing long-term delivery cost reduction.
Designed and implemented a delivery capacity check parallelization algorithm that decreased service latency by 50% as part of checkout flow, significantly improving system throughput and contributing to Amazon's ultra fast delivery goal.
Modernized the Australian driver onboarding funnel by automating critical vehicle data collection, achieving feature parity with US/UK markets. Eliminated manual survey workflows to save operational hours and improved data accuracy for precise, target-based recruiting.
Supported maintenance and on-call incident response for global services and mentored 2 engineers to drive engineering best practices and operational stability.
